Are the Extra Years Worth Living? The Quest for Healthy Life Expectancy in the UK

As she sat in her favourite armchair, basking in the afternoon sun streaming through the window, 82-year-old Margaret Wright reflected on her life. “I’ve seen things that most people only read about,” she mused. Yet, beneath her warm smile lay the reality of her daily struggle with chronic arthritis and the lingering effects of a stroke five years ago. While life expectancy in the UK has climbed steadily over the centuries, the question lingers: are these additional years being enjoyed in good health?

How do we measure HLE?

The elusive metric of Healthy Life Expectancy (HLE) provides a sobering perspective on this question. According to the Office for National Statistics (ONS), HLE is defined as the average number of years an individual can expect to live in “very good” or “good” health based on self-reported data. Unlike traditional life expectancy, which uses mortality rates, HLE involves complexities arising from subjective perceptions of health.

“HLE is inherently more challenging to calculate,” explains Dr. Emma Thomas, a leading researcher in public health at the University of London. “The reliance on self-reporting brings a layer of subjectivity and potential inconsistency across different data sources.” While life expectancy figures have been reliably tracked since the 1840s, HLE data are relatively recent, with reliable figures emerging only after 2000.

How has HLE changed over time?

The most recent data from the ONS reveals that male HLE at birth in England has dipped to 61.5 years for the period 2021 to 2023, while females fare slightly better at 61.9 years. Notably, this marks a decline from pre-pandemic levels, with males experiencing a 1.7-year drop and females 1.9 years since 2019.

“The COVID-19 pandemic has undoubtedly exacerbated health issues,” notes Dr. Sarah Elmore, an epidemiologist at Imperial College London. “While life expectancy soared for decades, the pandemic disrupted that trend, particularly affecting younger generations.” A stark contrast emerges when comparing age groups: whereas those over 60 have reported higher proportions of life spent in good health, younger demographics have seen declines. This bifurcation underscores the shifting dynamics of health across the lifespan.

How does HLE relate to life expectancy?

HLE shares a complex, intertwined relationship with life expectancy. Although increasing life expectancy might suggest a parallel rise in HLE, this correlation is not guaranteed. The data indicate a mixed narrative; while overall life expectancy continues to rise, the health quality of life is becoming increasingly compromised.

The Office for Health Improvement and Disparities (OHID) illustrates this point with a hypothetical: if self-reported good health improved by just 2%, the HLE would jump by 1.3 years, while a similar change in mortality rates would only boost HLE by a mere 0.1 years. Thus, individual perceptions about health can significantly sway HLE outcomes.

How HLE varies by location

Geography further complicates the analysis of HLE. ONS data outlines stark regional disparities, with England boasting the highest HLE, followed by Northern Ireland and Wales. Southern and eastern regions in England report significantly higher HLE figures than their northern counterparts.

• Largest decline in HLE (2021-2023): 6.0 years for females in Peterborough
• Most significant increase in HLE: Hillingdon saw increases of 5.8 years for males and 6.3 years for females

Scotland’s data remains absent due to the later Census, further complicating a comprehensive understanding of HLE across the UK.

International trends

The WHO reports a global increase in HLE of 7% from 2000 to 2021, reaching an average of 61.9 years. In stark contrast, countries like Singapore and Japan have HLEs that soar to 73.7 and 73.4 years, respectively. The European Journal of Clinical Nutrition attributes Japan’s longevity to dietary habits, emphasising fish and minimizing red meat consumption. Overall, the UK’s rank at 28 out of 185 countries paints a picture of progress needed in nurturing a healthier populace.

What affects HLE?

The factors that shape HLE extend beyond mere biological determinants. Chronic conditions such as strokes, diabetes, respiratory issues, and mental health problems often cloud perceptions of well-being:

• Chronic conditions: leading to reported poor health
• Psychological factors: anxiety and depression significantly affect health perception
• Lifestyle choices: smoking and obesity correlate with health deterioration

Moreover, socio-economic status remains a critical determinant in health outcomes. Data shows significant inequalities in HLE particularly between the affluent and the deprived. For instance, those in the wealthiest areas enjoy over 80% of their shorter lives in good health, while the most deprived residents struggle to surpass 75% of an even shorter lifespan in similar conditions.

What could be done to narrow the HLE gap?

The urgency to improve HLE has seized the attention of policymakers. The UK government identified HLE as a critical gauge for health improvement efforts, encapsulated in the 2022 “Levelling Up the United Kingdom” white paper aiming to bridge local disparities. Initiatives focus on curbing obesity, enhancing health education, and promoting physical activity as essential measures for achieving these goals.

“The emphasis on early prevention cannot be overstated,” argues Lord Jenkins, a member of the House of Lords’ committee on ageing. “Fostering a culture of healthy living can drastically reshape the life trajectories of future generations.” Yet he cautions that without equitable access to healthcare innovations, disparities in health quality may only widen.

Final thoughts

The UK faces a pressing need to catch up in the realm of Healthy Life Expectancy, particularly as societal inequalities continue to grow. As people prepare for an imminent rise in the State Pension Age, fueled by health disparities, the age-old adage that “life is good” might ring hollow for many. As technology becomes integrated into healthcare, its potential for increased longevity and quality of life remains promising—but only if those benefits are accessible to all, rather than a privilege for the few. In this pursuit, the intersection of innovation and public health will play a pivotal role in defining the essential quality of the years we gain.
